A process for the extraction and purification of Paclitaxel from a natural source of taxanes, comprising extracting Paclitaxel with an organic solvent from a natural source of taxanes, and treating the raw material with a base or an acid to obtain a biomass by precipitation. The biomass is isolated and dried, and resin and natural pigments are removed. The biomass is then dissolved in acetone and at least one non-polar solvent is added, until a Paclitaxel-enriched oily phase is obtained. The Paclitaxel-enriched oily phase is then treated with a base or an acid to obtain a second biomass, which is recovered by precipitation and dried. A solution of the second biomass in a volatile solvent is chromatographically purified at least once and crystallized.

Controlled local delivery of chemotherapeutic agents for treating solid tumors
InactiveUSRE37410E1Reduced bioavailabilityShort half-lifePowder deliveryCosmetic preparationsIn vivoExtended time
A method and devices for localized delivery of a chemotherapeutic agent to solid tumors, wherein the agent does not cross the blood-brain barrier and is characterized by poor bioavailability and / or short half-lives in vivo, are described. The devices consist of reservoirs which release drug over an extended time period while at the same time preserving the bioactivity and bioavailability of the agent. In the most preferred embodiment, the device consists of biodegradable polymeric matrixes, although reservoirs can also be formulated from non-biodegradable polymers or reservoirs connected to implanted infusion pumps. The devices are implanted within or immediately adjacent the tumors to be treated or the site where they have been surgically removed. The examples demonstrate the efficacy of paclitaxel and camptothecin delivered in polymeric implants prepared by compression molding of biodegradable and non-biodegradable polymers, respectively. The results are highly statistically significant.
